I won't deny that Gondor was at its greatest extent but it was slowing losing that extent. It was now on the turning point of decline.

You say that if you conquere the land you lose soldiers but then gain men back from the lands you conquer. I agree with this but not in this instance. The old brown lands and eastward to Rhun had vertually no men in them to gain control of. You had the men of Rhavannion which aided Gondor but they were further North. So Gondor would have attacked, lost forces, succeeded in making the enemy retreat to Rhun but then have no men to gain back from the land it managed to retain.

I will await the quotes you send me The Might.

But i will say that Rob=vannion was further north. it was no where near the Old brown lands and Ered lithiu. It was parralel with the sea of Rhun.

Just to point out ladies, from a military perspective. It would be quite unwise to have a stronghold between two allied realms that would not only both see it as a threat but also had direct communication between each other (something that no one else on Arda had, save maybe the elves and that wasn't really 'long-distance'). Imagine if you're Germany (no offence to any Germanic habitants  you have no telephones only horses, where as both France (I know bad example) and ... (can't remember what countries are the other side of Germany, lol) have satilite telecommunication. Regardless of how powerfull each nation is France and ... can simultaneously attack by planning it ahead using such devices. I am of course refering to the Palantiri. That would give a heavy advantage to the men. Another advantage of having the palantir was that (if Angmar were indeed between the Isen and Gwathir) if the Witch King attack either Arnor or Gondor from there then the attackee (that is the person being attacked) could inform the other party who then could themselves attack the weaker undefended side, while the attackee retreated slightly in the middle drawing the forces of the Witch-King further into Arnor while allowing other parts of the army (or possible other allies) to move to the sides then once in place the Witch King would find himself stuck between pointy swords and pointy swords (and quite possibly a few pointy ears). Never wage war without first making sure you have good communication to your allies. Just some food for thought
Also as an added bit, thankyou those of you who voted me the wisest character in middle earth

Just as another added point behave or you'll be (ONLY KIDDING, I just wanted to use the emoticon, I just had my first exam so I'm a bit hyper)

I see we have an interesting discussion going on here.  Ok, so lets clear some things away.  It's clear that Angmar was first started in 1300 TA:
Evil things begin to multiply again.  Orcs increase in the Misty Mountains and attack the dwarves.  The Nazgul reappear.  The cheif of these comes north to Angmar.~Appendix B.

Mos, while the Atlas of Middle-earth is a very good reference book done by Karen Wynn Fonstad she did not have access to all of Tolkien's writings.  Eventhough if it is a good accurate source that I would recommend, I would not put what she wrote above what Tolkien wrote.  Though it is a good reference, it is not entirely accurate, as she didn't have access to Tolkien's Letters or HoME.

Gondor reached the height of it's power under Hyarmendacil's reign (which was about 150 years before the WK goes to Angmar).  During Hyarmendacil's reign it was said that "The might of Hyarmendacil no enemy dared to contest during the remainder of his long reign."~Appendix A: Gondor and the Heirs of Anarion

Hyarmendacil was the last of the Shipkings and his son Atanatar takes the throne, and Appendix A points out Gondor's power begins to decline, but there is no problems in Gondor until the reign of Valacar (son of Romendacil II):
So ended the line of the Ship Kings.  Atanatar Alcarin son of Hyarmendacil lived in great splendour, so that men said precious stones are pebbles in Gondor for children to play with.  But Atanatar loved ease and did nothing to maintain the power that he had inherited, and his two sons were of like temper.  The waning of Gondor had already begun before he died, and was doubtless observed by its enemies.  The watch upon Mordor was neglected.  Nonetheless it was not until the days of Valacar that hte first great evil came upon Gondor: the civil war of the Kin-strife, in which great loss and ruin was caused and never fully repaired.~ibid
So, Gondor's power started to decline after Hyarmendacil, but there were no major problems up until Valacar's reign (which was after Romendacil), and it was during Romendacil's reign when Angmar was first established.  As TM goes to show Romendacil strengthened up Gondor after it was neglected by his fathers and grand-fathers, it was during his time that the Pillars of the Argonath were built displaying the strength Gondor still had.  But it was probably too late, for as the quote goes to show Gondor was in decline and despite Romendacil fortifying Gondor it was his son Valacar that would be hit with Gondor's first troubles.  The fact remains that during Romendacil's reign Gondor was very capable and strong, especially during Romendacil's reign I should say, eventhough if it had been going into decline from the power during Hyarmendacil's reign.

More to come later...

I think both of you are confusing Hyarmendacil l with Hyarmendacil ll. Gondor was at its greatest under the influence of Hyarmendacil l:

In Appendix A (I, iv) to The Lord of the Rings the kingdom of Gondor at the summit of its power in the days of King Hyarmendacil I (Third Age 1015-1149) is said to have extended northwards "to Celebrant and the southern eaves of Mirkwood."

Also you will notice that its say that he reigned for 125 year from 1015. Therefore by the time the WK establishes his realm in 1350 Hyarmendacil ll would be dead assuming he lived a similar lifespan to his father.

Boromir88 - A good post but I will correct you - Angmar was sent north in 1300, but did not properly establish Agmar until 1350 - this is the confusion.

In Appendix A (I, iv) to The Lord of the Rings the kingdom of Gondor at the summit of its power in the days of King Hyarmendacil I (Third Age 1015-1149) is said to have extended northwards "to Celebrant and the southern eaves of Mirkwood.

I said Hyarmendacil ll died in 1300 assuming he lived as long as Hyarmendacil l. You need to read the posts properly, The Might.

Ahh thanks for clearing that up, The Might.

Still I say Gondor was two pushed to fight 2 ememies and later 4.

And also if the WK went in my location he would have only Gondor to deal with. Rivendell and Mirkwood would be too far away and Arnor was destroying itself. Therefore I think  he would prefer to face Gondor alone as opposed to all the lessar places in the North.
